Quick and dirty chuck stop
« on: December 04, 2014, 08:44:48 PM »
Tonight I have put together a lathe chuck stop. Took me a little over 1 hour, do not understand why I waited years to make something so useful. Thought to share it here, maybe it can be useful for others….or not….

My Harrison lathe has a MK4.5 taper in its spindle nose. I happen to have 2 sleeves MK4.5 to MK3 taper. Took the worst of both and reduced it such that it just a little out of the lathe spindle nose



Have some old machinable MK3 adaptor



and cleaned it up in the lathe with some emery paper (I always cover the ways when using emery paper)



Mounted it in the adaptor sleeve and marked the length



Cut to size with the bandsaw



Drill and tap M8 for about 30mm deep



Turned down a piece of steel of 12mm to 8mm and treaded it M8



The other side I turned down to 7.5mm (the crank taps for my V8 engine will be 8mm) and made a spare one for future use. Below it is mounted in the spindle nose



And a view with the chuck mounted



Finally a family shot of the parts



I know there are much better and more versatile design but for me this will do and the goal was to make something quick!

Jeroen:

Nice work and certainly solves the problem.

Will a 5C collet fit inside a MT4.5? My lathe has a MT5 in the spindle and I was able to make a MT5 to 5C adaptor. Add a draw tube to tighten the collet and its ready to go.

 

I've found it incredibly useful. I even found it can stay in place with a 3 or 4 jaw in place, so it can be used for a chuck stop also.

Thanks for the write up.

Thank you hugh. Nice solution you have on your lathe. I have a adaptor from MT5 to 5C, kept it when I sold my previous lathe. I am planning to make a Camlock-3 disk with a MT5 taper and put the C5 Adapter inside. I would like to be able to remove it quickly since many times I have some stock inside the spindle noise.  Hope I win the Christmas lottery, then I can quit working and finally finish all the projects from my wish list!

Thanks for showing your solution, I like it!
